Ezekiel decomposed the rectangle shown into three smaller rectangles. Then he demonstrated the Distributive Property by modeling the area of the entire rectangle in terms of the three smaller rectangles. Which equation could Ezekiel have used? answer choices:
1. 21(3 + 3) = 21(3) + 21(3)
2. 6(6 + 12 + 3) = 6(6) + 6(12) + 6(3)
3. 21(3 + 2 + 3) = 21(3) + 21(2) + 21(3)
4. 6(10 + 10 + 11) = 6(10) + 6(10) + 6(11)
